Abstract：
 This invention discloses a method of preparing fuel battery electro-catalyst by sulfide precipitation method. It belongs to fuel battery material preparation technique range. The preparing method is that carrier, oneor two kinds of noble metals, sulfide, pH value regulator, deionized water are added in the vessel. Then they are reduced to get electro-catalyst after filtrated and dried at 6110 degree centigrade, pH value 1-11 range, agitating for 1-10 hours. The purity of the catalyst is high, and its particle size disperse is narrow, the particle range is 1-6 nm, the crystallization is good, agglomeration is few. This invention can be used as electro-catalyst in proton exchanging film fuel battery, it can reduce noble metal dosage, reduce fuel battery cost, and provides possibility for commercialization of proton exchanging film fuel battery.
